The Pauli Probability Spectrum Carries the Pure-State Quantum Fisher Metric
E. A. Ramirez Trino, M. A. Rajabpour
Stabilizer Rényi entropies compress the distribution of squared Pauli expectation values of a pure quantum state into scalar measures of nonstabilizerness. Here we show that, befor…

Universal Crossovers of Stabilizer Entropy Beyond Criticality
Reyhaneh Khasseh, E. A. Ramirez Trino, M. A. Rajabpour
Stabilizer Rényi entropy has emerged as a probe of nonstabilizerness in quantum many-body systems, but its scaling structure beyond critical points remains poorly understood compa…

Stabilizer-Shannon Renyi Equivalence: Exact Results for Quantum Critical Chains
E. A. Ramirez Trino, M. A. Rajabpour
Shannon-Renyi and stabilizer entropies are key diagnostics of structure, non-stabilizerness, phase transitions, and universality in quantum many-body states. We establish an exact…
